Sets new arguments for the call control function that immediately follows it.

DWORD adiSetExtendedArgs ( CTAHD ctahd,
void *extargs,
size size)

ctahd CTA context handle returned by ctaCreateContext.

extargs Pointer to data structure containing extended arguments.

size Size of data structure extargs.

SUCCESS

• CTAERR_FUNCTION_NOT_ACTIVE
  This error is returned when a function call is made to ADI call control when the NCC service is active.
• CTAERR_INVALID_CTAHD

None.

This function sets additional arguments for the next call to adiAcceptCall, adiAnswerCall, adiPlaceCall, adiRejectCall, or adiReleaseCall.

The arguments set by adiSetExtendedArgs are only applicable to the next call. adiSetExtendedArgs must be repeated for subsequent calls.

The arguments to be sent are stored in one of several data structures, depending upon the next call control function to be invoked. Refer to the AG ISDN for Natural Call Control Developer's Manual for a list of these structures.
